原发性腹膜后恶性肿瘤的手术治疗

目的:探讨原发性腹膜后肿瘤的诊断与治疗。方法:对经手术治疗的9例原发性腹膜后肿瘤的临床资料进行回顾性分析。结果:原发性腹膜后肿瘤最常见的临床表现为无症状性包块(6/9),组织学类型繁多,本组分别为脂肪肉瘤4例、平滑肌肉瘤2例、副神经节瘤2例、间叶瘤1例。本组病例手术切除率为77.78%(7/9)。2例部分切除患者因术后肿瘤迅速复发增大,短期死亡;2例术后复发再手术患者1例于再手术后1年半死亡,余5例仍健在。结论:原发性腹膜后肿瘤的临床表现多为无症状性包块,组织学类型复杂,以脂肪肉瘤多见,完整切除是惟一有效的治疗方法,也是降低术后复发的主要措施。

Therapeutic Efficacy of Primary Retroperitoneal Tumour Treated by Surgical Operation in 9 Cases

Objective:To evaluate the diagnosis and treatment of primary retroperitoneal tumour(PRT). Methods: The clinical data of 9 cases of PRT were analyzd retrospectively. Results: The most common manifestations of PRT in this group of patients was abdominal mass without pain (6/9), and pathological patterns of them varied (among which lipoblastoma 4 cases, leiomyosarcoma 2 cases, paraganglioma 2 cases, mesenchymoma 1 case). The resection rate was 77.78%(7/9). Two patients with partial resection died quickly for tumour enlargement. Two patients received second operations for recurrence, 1 patient died 1.5 yrs later and the other lived well. The remained 5 cases were alive and well. Conclusions: The most common clinical manifetation of PRT is abdominal mass. Their pathological types is complicated, among which the lipoblastoma is most common. Complete resection is the only effective method for the treatment of PRTs, and it is one of the major factors in reducing recurrence.
